Simulator made in PHP does not appear calculation result

[alexndrre]

Hello people! Well, I'm working on a site that has a financing simulator that asks for your data and a value related to cars, real estate and motorcycles. When simulating, it sends you to a page, calculating the closest result and sends your data to the database. However, he has a problem now. When you try to simulate, it no longer shows the result, it even loads the table but has no content, and the simulator form quickly pops up again. Check out an example at http://vitorconsorcios.com.br/simulador.php, below has the source code of the site. I've tried everything, but this is my last solution. What could be the cause of this?

 

<?php
include("injection.php");
/* if (isset($_POST['valorcon']) */
$valorcon = (int) tira_virgula_para_ponto( $_POST['valorcon'] );
$plano=anti_injection($_POST["plano"]);
$tipo=anti_injection($_POST["tipo"]);
$nomecon=anti_injection($_POST["nomecon"]);
$telefone=anti_injection($_POST["telefone"]);
$emailcon=anti_injection($_POST["emailcon"]);
$cidadecon=anti_injection($_POST["cidadecon"]);

if ($valorcon>0) {        
    // Inseri a procura
    $tsql = " insert simulacao set
                        plano='$plano' ,
                        tipo = '$tipo' , 
                        valor = $valorcon  ,
                        nome = '$nomecon' ,
                        telefone = '$telefone' ,
                        email = '$emailcon' ,
                        cidade = '$cidadecon' ";
    //echo $tsql;
    //exit;
    $sql_insert = fbd($tsql,"","inserir simulacao");

Not trying to be difficult here but I want to ask - What has changed in your code?  Working scripts that suddenly don't work usually means you changed something.  Have you tried adding any kind of debugging code (echo's or writes to a text file) to track the actions that your script is taking?

No updates or changes have been made. I had not moved this part, just made a backup and it was like this.

Personally I would abandon trying to fix the code and instead rewrite it using PDO. Since it uses deprecated code that is going away in any case, it makes no sense to waste time trying to fix it.

[ginerjm]

And I would learn how to structure your scripts to separate the logic (PHP) from the presentation (HTML/JS) so that it is easier to read/understand and maintain.  As it is your script is very hard to follow.   A good style would be to place your php at the beginning and your html at the end and your js embedded inside of that HTML.  Test the current status of the script's execution (is this the first time in here? or not?) to determine what you php code should do and avoid trying to handle things from the form that don't yet exist.  A nice clean method of writing php scripts would leave you with just one pair of php tags (<?php & ?>) in it.

[ginerjm]

But - getting back to your original question.  If the script used to work and now it doesn't something has changed.  If not the code then, as Barand said, it must be your environment.  PHP Version?  Default folders in use? .INI settings?   I mean - what has changed?  We know something has, you just have to find it.  Basically - what is the difference between the time when it did work and now?   

Do you have php error checking turned on in your ini?  Have you checked the error log file?   

[alexndrre]

That was fixed. Because of the language signals, the database was under one name and php another.

Thank you!
